Integration weights support

[alecandido]

Another example is the computation of the integration weights, I believe that also in laboneq there is an implementation (which is what Juan initially followed for the implementation in qibocal).

@andrea-pasquale, integration weights are certainly something you want to apply online, because otherwise it forces you to do raw acquisitions, that has plenty of other limitations.
So, all QUA, laboneq, and Qblox as well expose it. But they are even already exposed in Qibolab

qibolab/src/qibolab/_core/components/configs.py

Lines 102 to 104 in 577b91f

	kernel: Annotated[Optional[NdArray], Field(repr=False)] = None
	"""Integration weights to be used when post-processing the acquired
	signal."""

So, it's mostly a matter of drivers' support (and calibrating them, of course).

[alecandido]

Qblox-wise, they will be supported very soon after the driver will become available (if not right at the same time)

QM-wise, they are in principle supported but I believe never tested so I would prefer to test first before saying anything for sure. I remember once I tried, there were some limitations (you can have at best one weight per four samples or something like that) that may be different from instrument to instrument, so it's certainly worth further investigation.
